Abstract: It is a common phenomenon that borrowing and lending material in Make to Order (MTO) type of iron & steel manufacturing factory, which brings difficulty in material tracking. To deal with this problem, an algorithm of material dispensing and tracking was presented while order was changed. The balancing rules for material borrowing and lending were introduced based on graph model. And the change of orders due-date resulted from material dispensing was analyzed. So an optimized mathematic model for material dispensing was put forward. This models objective function was to minimize cost of both stock and task lateness. It could be regarded as a kind of special transportation problem that unit cost was associated with the transportation scheme. Key steps on solving this special problem with tabular algorithm were provided. Finally, effectiveness of this method was verified by an example.
